Today, the Russian government announced they have banned imports of a variety of Western products. The sanctions are a retaliation to last week's increased sanctions by the United States and Europe, targeting banks, imports and the energy sector.

Russian prime minister Dmitri Medvedev announced the sanctions, which ban all dairy, fruit, vegetables, beef and pork from the United States, Canada, European Union, Australia, and Norway. The import ban will be in effect for one year. Medvedev also announced Ukrainian airlines could no longer enter Russian air space.

"We hoped until the very last that our foreign colleagues would realize that sanctions are a dead end and that nobody needs them," said Medvedev, "Things have turned out in such a way that we have to implement retaliatory measures."

Russia will also consider additional aviation sanctions, such as an air ban over Siberia. This would be an inconvenience to all American and European air travel to Asia, adding to fuel costs as well. They are also debating an import ban on planes, navy vessels and cars.

News reports are focusing on the Germanwings pilot's possible depression, following a familiar script in the wake of mass killings. But the evidence shows violence is extremely rare among the mentally ill.
